系统评价单纯针刺治疗原发性高血压的疗效。

检索中国期刊全文数据库(CNKI)、万方数据知识服务平台(Wanfang)、维普资讯中文期刊服务平台(VIP)、中国生物医学文献数据库(SinoMed)、PubMed、Cochrane Library、Embase、Web of Science建库至2024年2月29日单纯针刺治疗原发性高血压随机对照试验（RCT）文献。对纳入文献进行资料提取和偏倚风险评价后，采用Revman 5.4软件进行Meta分析。

纳入RCT文献19篇，共1738例患者，Meta分析结果显示：针刺在提高降压有效率［RR=1.10，95%CI（1.01，1.20），P=0.03］，降低患者收缩压［MD=-5.55，95%CI（-9.85，-1.25），P=0.01］、舒张压［MD=-5.27，95%CI（-8.74，-1.80），P=0.003］方面优于西药；针刺在降低患者舒张压［MD=-2.11，95%CI（-3.95，-0.26），P=0.03］方面优于假针刺，但与假针刺比较，针刺在降低患者收缩压方面差异无统计学意义［MD=-3.52，95%CI（-10.57，3.54），P=0.33］；针刺组的不良反应发生率［RR=0.19，95%CI（0.08，0.42），P<0.001］较对照组更低。

单纯针刺可有效降低患者收缩压、舒张压，提高降压有效率，且不良反应少。但受纳入文献数量和质量的限制，上述结论尚需开展更多研究予以验证。

To systematically evaluate the efficacy of pure acupuncture in the treatment of essential hypertension.

Databases including China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, VIP Chinese Journal Service Platform, Chinese Biomedical Literature Database (SinoMed), PubMed, Cochrane Library, Embase, and Web of Science were searched for randomized controlled trials (RCTs) on pure acupuncture for essential hypertension, from database establishment to February 29th of 2024. After data extraction and bias risk assessment of the included studies, Meta-analysis was performed using RevMan 5.4 software.

A total of 19 RCTs involving 1738 patients were included. The Meta-analysis results showed that: compared with Western medicine, acupuncture was superior in improving the effective rate of blood pressure reduction ［RR=1.10, 95%CI (1.01, 1.20), P=0.03］, reducing patients' systolic blood pressure ［MD=-5.55, 95%CI (-9.85, -1.25), P=0.01］ and diastolic blood pressure ［MD=-5.27, 95%CI (-8.74, -1.80), P=0.003］； compared with sham acupuncture, acupuncture was superior in reducing patients' diastolic blood pressure ［MD=-2.11, 95%CI (-3.95, -0.26), P=0.03］, but there was no statistically significant difference in reducing systolic blood pressure between acupuncture and sham acupuncture ［MD=-3.52, 95%CI (-10.57, 3.54), P=0.33］; the incidence of adverse reactions in the acupuncture group was lower than that in the control group ［RR=0.19, 95%CI (0.08, 0.42), P<0.001］.

Pure acupuncture can effectively reduce patients' systolic and diastolic blood pressure, improve the effective rate of blood pressure reduction, with fewer adverse reactions. However, limited by the quantity and quality of included studies, the above conclusions need to be verified by more researches.
